"An out of bounds write was discovered in Blink. If a user were tricked
in to opening a specially crafted website, an attacker could
potentially exploit this to cause a denial of service via renderer
crash, or execute arbitrary code. (CVE-2016-1660)

It was discovered that Blink assumes that a frame which passes
same-origin checks is local in some cases. If a user were tricked in
to opening a specially crafted website, an attacker could potentially
exploit this to cause a denial of service via renderer crash, or
execute arbitrary code. (CVE-2016-1661)

A use-after-free was discovered in the V8 bindings in Blink. If a user
were tricked in to opening a specially crafted website, an attacker
could potentially exploit this to cause a denial of service via
renderer crash, or execute arbitrary code. (CVE-2016-1663)

It was discovered that the JSGenericLowering class in V8 mishandles
comparison operators. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to obtain
sensitive information. (CVE-2016-1665)

Multiple security issues were discovered in Chromium. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to read uninitialized memory, cause a denial
of service via application crash or execute arbitrary code.
(CVE-2016-1666)

It was discovered that the TreeScope::adoptIfNeeded function in Blink
does not prevent script execution during node-adoption operations. If
a user were tricked in to opening a specially crafted website, an
attacker could potentially exploit this to bypass same origin
restrictions. (CVE-2016-1667)

It was discovered that the forEachForBinding in the V8 bindings in
Blink uses an improper creation context. If a user were tricked in to
opening a specially crafted website, an attacker could potentially
exploit this to bypass same origin restrictions. (CVE-2016-1668)

A buffer overflow was discovered in V8. If a user were tricked in to
opening a specially crafted website, an attacker could potentially
exploit this to cause a denial of service via renderer crash, or
execute arbitrary code. (CVE-2016-1669)

A race condition was discovered in ResourceDispatcherHostImpl in
Chromium. An attacker could potentially exploit this to make arbitrary
HTTP requests. (CVE-2016-1670).
